VAPO R-STOVE.

SPECIFICATION forming part of Letters Patent No.A 268,871, dated December 12, 1882.

I Application filed May 9, 1882. (No model.)

' To all whom it may concern will first be described, and those parts or-com- `binations which constitute the invention will Y then be designated in the claims.

In the drawings hereto annexed, Figure lis a perspective `view of a vapor-stove embodying my improvements. Fig.2is asection of aleat', of which one or more are hinged to the stovetop. Fig. 3 is a view of the slide-arm which supports the leaf. Fig. 4 is a side view ofthe burner, a part being in section. Fig. 5 is a top view of the burner. Fig. 6 is a vertical section of a part of same. Figs. 7 and 8 show the grooveand the segmental arm and the means by which the inner end of the arm is supported.

ln the drawings hereto annexed, the letter .A denotes the oil-fount; b, the pipe leading therefrom to the burners; C, the stand which supports these and all other parts. In the present example the stand is shown provided with two burners, D, which are arranged, as usual, immediately below the stand-top, which is preferably made of cast-iron in the form of 'open grating. In the drawings this is partially shown bythe circular-shaped open-work D', which permits the heat and liame from the burner to pass up to the cooking-vessel which `rests upon the top. A leaf, E,is provided on one edge, with one or more hooks, e, which Vcurve laterally from one surface of the leaf,

forming a segment ot' a circle. This hook constitutes one part of a hinge, of which a slot,f, near the edge of the table-top, forms the other part. The hook being entered into the slot from the lower side, the leaf is in no danger of being lifted out. A segment-shaped arm, g, is fitted to slide in a similarly-shaped groove, l1, formed in the stand -top, and said arm is it may be grasped to facilita-te its movement.-

By moving this arm ont when the leafis elevated to a horizontal position it serves to sustain the leaf', and by moving the arm back the leaf' may be dropped or swung down. The means by which the outer end of the arm is supported is shown in Fig. 7. When the arm is moved back under the table-top its inner end is' supported by the lateral projection of a lug,71/, attached to the under sideof the tabletop alongside of the groove h and about midway of its length. The knob g on the inner end of the arm occupies the groove h, and, besides serving as a grasp, keeps the arm from moving laterally, and thereby retains it -upon the aforesaid lug. By inakingthe supportingarm segment-shaped it affords the advantage of sliding partly around the circular shaped open-work D' in the top, through which the llame rises.

The burner D is constructed with special reference to adapting it to be used for cooking purposes, the object bein gto produce four non'- luminous llames or jets, which shall be so arranged with respect to each other as to form the four corners of a quadrangle, and by th us being spread to cover a broad surface, will be suit-ed for heating the bottom ot' a cookingvessel.

To an inverted T-piece, t', a nozzle-piece, k, is secured. The oriiice consists of a fine jetaperture, l, which is closed by the upwardlyprojecting point of a needle-valve, m. A vertical tube, u, is secured end wise to the nozzle and about the `jet-aperture, and this tube is provided with air-inlets 2. At the upper end of this tube is a single, double, triple, or fourway connection, p, and to each adown wardlycurved flametube, q. is attached, the lower ends of these dame-tubes being open, and all entering one large air-supply tube, fr, which is closed at the upper end, but open atthe lower end to admit air. The lower end should be so constructed that while it admits air portions of it will be in direct contact with the nozzlepiece lc, in order thereby to conduct heat to the same. Each llame-tube has a slit, 3, in the downwardlycurved part, which is readily made by a saw.

The operation may be described as follows:

IOO

2 essere The valve mis turned toallowajetof thelight hydrocarbon Huid to be thrown into the v'ertical tube n, and the'valve is then closed.l The uid may then be ignited by applying a dame to the holes 2. As soon as the parts are sut'- Aliciently heated the valve m should be opened again, and the jet ot fluid, then escapinginto the heated tube n, will be instantly converted into vapor. Air will then enter the tube u through the holes 2 and be mingled with the vapor, and the mixture will passup the heated tube and out the four branchesp to the flameslits 3 in the downwardly-curved tubes. Atv

stand-top, and will heat any vessel placed thereon. A drip-pan, L, is placed below the burners to catch drippings of'uid from the burners. The legs ot' the stand are provided with rollers or casters S to facilitate 'the movenient ot' the apparatus. v

Having described myinvent-ion, I claim and desire to secure by Letters Patent ofthe United Statesl. The combination, with the stove-top provided with a segment shaped groove, It, of'a leaf', E, hinged to the top, and a segmentshaped arm, g, arranged to slide endwise in the said groove, as set forth.

2. A vapor-stove burner consisting of a nozzle-piece, lc, a vertical vaportube, n, secured endwise above the nozzle, an air-supply tube, i', closed at its upper end andopen atits lower end and surrounding the vertical vapor-tube, and one or more downwardlycurved flame tubes, q, one end ot' which connects with the vertical vapor-tube and the other end with the air-supply tube, as shown and described.

ln testimony whereot1 l affix my siguaturein` 'presence ot' two witnesses.
